Make sure the changelog mentions files whose flags changed These changes don't actually need a new filelog entry (see next patch), but if we don't mention the files in the changelog, it becomes much harder to find all changesets that touch a file (not even a "hg log --removed file" will work).

#!/bin/sh

hg init
touch a
hg add a
hg ci -m "a" -d "1000000 0"

echo 123 > b
hg add b
hg diff --nodates

hg diff --nodates -r tip

echo foo > a
hg diff --nodates

hg diff -r ""
hg diff -r tip -r ""

true
